I live right now in the apartment and have a free room to share. It could be that I am during your stay not at home - however if I am there, I am happy to support you with getting around. ;)
It is a neat place with a great balcony view over central Tokyo. I use this apartment for living purposes, so expect to dive into a typical household. You can expect a clean room, it is as the pictures show. ;)
Your room has an AC available! (believe me, in summer more than necessary)
The apartment is located in the heart of Tokyo within a calm neighboorhood with access to supermarket, convience etc. in walking distance (<5 minutes).
3 metro stations are in close distance (8-10 minutes walking for each) and allow an easy access to all spots within the city. Shinjuku station is 20 minutes away by walking.
